7.3 Calibration
The STORMBEE with the FARO Focus scanner mounted on it should be calibrated at regular intervals
or after maintenance or repair to ensure the relative location and attitude of the GNSS module
components with respect to the FARO Focus scanner are still accurate. Otherwise the margin of error
after post-processing will be larger than normal.
Currently, this calibration can only be done by Think 3D. However, to do this calibration, Think 3D only
requires the user to send (over internet) the point cloud data files of one of the last flights in which a
Hashtag (#) manoeuvre is performed (Figure 7.2). Afterwards, you will receive the new correction
factors which you should implement in the config.ini file used by BEEFLEX (see separate PDF
“ STORMBEE Software User Manual ” on how to do thi s).
STORMBEE operators should send through a (calibration suitable) set of scan and GNSS data to Think
3D every 6 months or 20 hours of flight time (roughly every 150 flights), whichever comes first.
The Hashtag (#) manoeuvre consists of flying automatically horizontally along the lines of the shape of
a hashtag in the vicinity of some form of infrastructure while the scanner is active. There needs to be
some form of infrastructure (road, building) nearby as the calibration will be done with respect to this
infrastructure. You do not
need to fly this manoeuvre in “crab” (heading 20° offset with respect to
flight direction), simply fly it with nose forward. As this manoeuvre takes little flight time (roughly 2
minutes), one can simply perform it at the end of an inspection flight when sufficient battery is left.
There is no need to perform a separate flight.
